Abstract

Continuous-relief diffractive optical elements have been replicated by use of conventional compact disc injection-molding techniques. Two continuous-relief microstructures, a blazed grating and a fan-out element, were chosen to evaluate the replication process. Original elements were fabricated by directwrite electron-beam lithography. Optical measurements and atomic force microscopy were used for investigating the replication fidelity.
